Title: Improvements in steam or like valves
IPC: F16K41/16
Filed: 1919-11-22
Abstract: 155,442. Foster, W. H. Nov. 22, 1919. Taper plug lift and wedge valves; actuating - mechanism.-In a steam or like valve in which a screwed spindle engaging with the valve is held against longitudinal movement, a domeshaped ring is inserted between the valve body and a collar on the spindle to prevent the longitudinal movement of the latter. The valve b is prevented from rotating by ribs a<1> entering recesses b<1> in the valve, and is moved longitudinally by a screwed rod d engaging with a screwed recess. Alternatively, a screwed recess at the lower end of the rod engages with a screwed rod projecting from the valve. The spindle d is provided with a collar d<2> which is held between the bottom of the stuffing- box and a domed ring i which rests on the shoulder h. The space i<2> serves partly to accommodate the valve when raised. If the meeting faces of the members d<2>, i, h are ground, the passage of steam to the lower side of the stuffing-box is reduced.

Abstract: 395,213. Electric signalling systems. JONES, J. H., Victoria Garage, Great North Road, Milford Haven. Oct. 20, 1932, No. 29317. [Class 40 (i).] A system for indicating electrically the quantity and quality of liquid fuel delivered by a pump comprises a row of lamps 12 selectively operated by a contact 2b on the pointer 2 which is set manually to determine the quantity of liquid to be delivered and a row of lamps 13 controlled in accordance with the position of a cock 6, which selects the grade to be supplied, to indicate the quality. The cock is provided with contacts 21 connected to the lamps 13 and co-operating with a fixed contact 22 to select one of the " quality " lamps according to the setting of the cock. Both sets of lamps are mounted in a casing 14 having a translucent front carrying suitable indications. The selected lamp circuits are closed by a switch 11 which also switches on the motor for operating the pump. To direct the attention of an attendant to the indicator, an audible alarm 23 is operated during movement of the switch 11. Instead of lamps, movable indicators may be employed.

Title: Improvements in or relating to electron permeable electrodes
IPC: H01J31/50
Filed: 1937-10-28
Abstract: 504,927. Electron multipliers. McGEE, J. D. Oct. 28, 1937, Nos. 29426 and 33884. [Class 39 (i)] [Also in Group XXII] An electrode for use in electron multipliers comprises a thin film supported on a mesh structure ; the impingement of electrons on one side of the film causes emission of secondary electrons from the other side. The interstices of mesh may be 0À1 mm. in diameter with a shadow ratio of 10 per cent and are sufficiently small to support the film against air currents encountered in a room during assembly. The mesh, which may be made by electrodeposition and mounted and stretched as described in Specification 479,024, is immersed in a solution of cellulose acetate or collodion in acetone and withdrawn at an angle so as to leave solution in the meshes. When the solvent has evaporated, the metallic film is applied, as by sputtering, and the cellulose or collodion film is dissolved away, leaving the metal film on the mesh. To avoid local variations of surface tension likely to disrupt the film, the solution is performed slowly by starting with a nearly saturated solution and gradually diluting it. The film may comprise more than one metal layer; for example, caesium may be applied to oxidized silver. The thickness of the film is preferably such as just to prevent the incident electrons emerging from the other side. The electrodes may be used in an image intensifier with the final screen fluorescent or mosaic, focusing coils being provided between each electrode. In a modification to avoid focusing, the electrodes 4-7, Fig. 2, are placed so close together that lateral spreading cannot occur. The mesh supports are aligned so that they reduce the impenetrable area and assist focusing. If the meshes are coated with insulation such as lithium borate or alkali fluoride, the electrodes may be placed in contact. In the form shown the electron stream from photo-cathode 2 is amplified by the electrodes 4 ...7 and falls on a double-sided mosaic 9. Focusing coil 8a and grid 8 may be dispensed with and the mosaic (or a fluorescent screen) placed close to electrode 7. The large capacity between the mosaic and the other electrodes may reduce its sensitivity and this is avoided by high resistances placed in the leads to electrodes 4 ... 7. Specification 457,493 is referred to.

Abstract: 1,115,446. Lubricating. TRACTOR RESEARCH Ltd. 23 March, 1966 [12 July, 1965], No. 29465/65. Heading F2A. An oil collector and distributer device scoops up oil adhering to a rotating member and distributes it to bearings. In Figs. 1 and 2, two collectors are arranged back to back so that one will be in operation during rotation of a crownwheel 3 in either direction. Each collector has an opening 18, 19 in a wall 11, 12 below which opening the edges of the base are chamfered to form a scoop. Oil from opening 18 passes to respective bearings from outlet 20 in wall 15, from outlet 28 in wall 13 and channel 27, and from outlet 32 in wall 16 and duct 23 and channel 30. Similarly, oil from opening 19 passes from outlet 21, from outlet 31 and channel 30, and from outlet 33, duct 24, well 26 and channel 27. Outlets 20, 21, 28, 31 are dimensioned so as to restrict flow so that when the device slopes the oil level in the respective collector rises and all outlets are operative. The device may be of resilient material. The device is supported by adjustable angle pieces in Fig. 6 (not shown) and by spring clips in Fig. 7 (not shown).
Patent GB-1553468-A (GB)
Title: Control valves
IPC: F16K17/32
Filed: 1977-07-14
Abstract: An installation control valve, for example for use in a fire fighting sprinkler installation, comprises a pivotal butterfly valve disc co-operable with a movable stop, which in one position abuts the valve disc to retain the valve closed against pressure forces acting thereon. A retaining mechanism is releasably held to resist stop movement and so prevent valve disc opening but is operable under a predetermined condition to permit stop movement from said one position to a second position. When the stop is in the second position, unequal pressure forces on either side of the valve disc cause same to move thereby opening the valve.

Title: Improvements in or relating to change speed mechanisms
IPC: F16H3/72
Filed: 1936-11-02
Abstract: 478,223. Variable - speed gearing. SCHMID, F. Nov. 2, 1936, No. 29810. [A Specification was laid open to inspection under Sect. 91 of the Acts, May 5, 1937.] [Class 80 (ii)] Relates to planetary variable-speed gearing in which a driven shaft 1a, Fig. 1, carries stepped planets 3, 14 meshing respectively with a pinion 2 fast on a driving-shaft 1 and with a loose sun 15 the speed of which is regulated by throttling a plunger pump. The planets, which are supported in a box 5 fast on the shaft 1a, are triple in character, and steps 11 projecting on the driven-shaft side mesh with a loose sun 10 adapted to be held by a brake 12 so that a fixed ratio drive imparted to the shaft 1a is a reversed one. The sun 15 rotates loosely about a hub 5a of the carrier 5 and is integral with a disc 17 which carries three hydraulic cylinders 18, Fig. 2, which open inwardly towards an eccentric 22 fast on the hub 5a. Relative motion in the gearing caused by relative slip back of the shaft 1a causes relative turning of the eccentric 22 inside a strap 20 connected to three pistons 19 so that these pistons reciprocate radially and cause a circulation of oil in an annular connecting chamber 24. Throttling of this chamber 24 to produce varying drives upon the shaft 1a is effected by moving valves 23, Fig. 3, across the chamber from a muff 27, Fig. 1, which slides on the shaft 1 under control from a manual lever 29. Arrangements are described in which the annular circulation chamber is radially within the circle of hydraulic cylinders. In one of these, the eccentric is formed internally on a flange of the planetcarrying box. In another arrangement, the eccentric is centrally arranged but divided on each side of a cylinder block and there is a crosshead across the outer end of each cylinder. In this form, there is a pawl to prevent the carrier box from turning backwards, so that there is a definite low speed with increased torque. In this form also, suction valves are carried by the pump pistons to replenish the oil in throttled circulation.
